To all whom it may concern Be it known that I, HENRY J. QHiL'roN, a citizen of the United States, residing at l the city of Chicago, county of Cook, and

State of Illinois, have invented certain new and useful Improvements in Bottle-Washing Apparatus, of which the following is a specification.

This invention relates to improvements in bottle washing apparatus and refers more particularly to a rotary washing machine for cleansing milk bottles and the like.

Among the salient objects of the invention are to provide a construction in which a plurality of bottles are carried by a rotary main frame and a series of washing operations automatically performed upon the bottles; to provide a construction in which the bottles are automatically lowered into and raised out of a tankof water and while so lowered washed both interiorly and exteriorly; to provide a construction in which the exteriors of the bottles are automatically rinsed during their travel after they have been subjected to the aforesaid washing operations; to provide a construction in which the bottles are automatically shifted into and out of alinement with the washing and rinsing apparatus at predetermined intervals and in which the bottles are also so shifted as to permit the operator to readily remove or replace them in the bottle holders; to provide a construction in which the bottles are soaked during the entire washing operation and during their travel around the machine; to provide in a construction of the character referred to mechanism for more effectively washing the interior of the bottles; to provide a construction in which the exteriors of the bottles, after being washed are first rinsed with hot water and then sterilized by steam; to provide simple and improved compensating. mechanism for washing botties of di 'ent tjr'unequal sizes; to provide means per ,imtting"the air in the bottles to esgafie .vvhnfitheir interiors are being washed 7 I readilykenterthe bottles; to provide in a construction of the above character means for automatically cooling the bottles after they have been subjected to the washing and rinsing operations in order that they may be more readily removedby the operator; to provide simple and improved means for automatically performing the washing and Specification 01' Letters Patent.

Referring to the drawings, 1 designates the base casting of the machineat either side of which is supported a pair of standards 2 which carry an upper frame casting designated as a whole 3. Between these castings is mounted a rotary main frame. 4. This main frame consists essentially of a base support 5 carrying a water tank 6,.

by means of screw bolts shown at 9. Thepost is also preferably secured to the base of the rotary,main,frame W'atcr isisupplied to the tank of a main' supply pipe 11 and an extension 11' which extends into the'hollow upri ht 7. This pipe is controlled by a' suita le vallvel2. In order that the water may pass from the central upri ht 7 into the tank, the formeris apertured, at its lower'end as shown'at 13. The tank is provided'with an over-flow pipe 14. .Withinthe tank are mounted a plurality of brushspindles 15 carrying'brushes '16. The lower ends ofv these spindles are rotatably journaled in suitable sockets 17 in the bottom of the tank while the upper ends ofthe spindles are similarly journaled in sockets 18 carried bythe upper casting '8 ofthe rotary main frame.

Referring now to the bottle holders, upon the upper edge of the tank is mounted a ser es of "journal brackets or trunnions 19 which carry posts 20; These posts extend in which is seated a compressionspring 27,

the upper end of which bears against a collar 28 threaded to the inner sleeve 22. To each sleeve is secured a supporting bracket 29 by means of a split collar 30 and through bolt 31; These brackets 29 are provided with bosses 32 extendin vover the brush spindles 15. spindle is mounted a gear 33 which is splined to the spindle by means of'a feather 34 in such. a way as to permit the boss and gear sliding vertically on the spindle. As

shown at 35., the gear is provided with as'lceve screw-threaded to the lower end of (he boss. Each of these-brackets is also provided with two bosses 36in which are mounted the spindles lilach of these spinners 38' is adapted to fit each inner sleeve 22 over the upper -e nd of an inverted liiottle and both manner he end of eac- 39, to'a piifi 140 which meshes with an idler er and spin the same me a tel; described;

The spinning and centering devices are so arranged as to compensate for any small inequalities in the size of the bottles. T 0 this The arms 45 of this equalizer engage upp r end of thespinner spindles 37' a low -for a differential movement therein,

in engagement with the bottles cally upon the posts 20 by loosening the various sizes of bottles. In'this connection it will be-noted that the gears 33jare so limited vertical movement-thereon when thebrackets 29-are adjusted.

and lowering the bottle holders, 'each of the brackets 24 is provided with a, boss 46 in which is journaled a cam roller 47 riding on' a cam track- 48 which extends entirely around the machine. This cam track 48 is carried by arms 52 secured as shown to the upper stationary casting 3. As shown more clearly in Figs. 1 and 3 this cam track portions b and a respectively.

between the end of the bushing and the inner face of the nut is seated a packing 61.

The lower end of the inner bushin 56 extends through the outer bushing and is providcd with a pinion 62 keyed to the bushing as shown at 63. These pinions from a common circular gear 64. This gear 64 is provided with a hub 65 journaled on a shoulder 66 carried by the lower main casting 1. secured a circular beveled gear G7 which is driven from a pinion 68 carried by the main shaft 69. The latter is journaled in suit able bearings 70 carried by the base 1 and is driven from a pulley 71.

The inner brushing, spindles 55 are provided with spiral blades 72 in order to more thoroughly agitate the water while the interior of the bottles is being washed. The upper ends of the hollow spindles 55 extend above the water line in the tank and inasmuch as these spindles are open at either end, the air in the bottles escapes through the spindles 55, thus permitting water to readily enter the bottles.

To insure of the brushes readily entering the neck of the bottles I provide a series at posts 72 provided with a reduced threaded extension H which is threaded into the bus-1' of the rotary main frame. Upon each of 'lhe brackets 7:) are connected to the sleet; I 22 in such a way that the sleeves support the brackets but at the same time are tree 3 rotate mdc undent of the brackets. Acco ingly the lower end of each sleeve 22 is p vided with a flange 78 which rides in forked arm 79.

Ref rring now to the manner of lllliS the interior of the bottles, in the lower n.

of the rotary main frame is screw threath a bolt 30 which supports an annular cas it 8i. This casting held in yicldaolev er. gagcment with the lower end of the vote? tank by means of a coil spring 82 ins l between the base of the casting and the 83 of the bolt. This casting is provide its upper end with a pair of segmc chambers 84 and 85 respectively. From i of these chambers a plurality of duct load to the outer edge of the rotary -f' and terminate in forked extensions 87 wh communicate with vertical rinser pipes seated in the outer edge of the frame:

water is delivered to the chamber 85 b" means of a delivery pipe 89 and similarly steam is delivered to the chamber hr 62 are driven On the lower end of this gear 64 is casting these posts 73 is slidably mounted a braelwt means (1 a. pipe 90.

The operation of the machine is apparent from the foregoing description. It will be noted, however, that when the niachine is first started, only the one pair of bottles is inserted in each of the sets of holders and -these automatically lowered into the tank and washed and soaked. When the bottle holders are raised out of the tank the operator fills the other pairs of bottle holders and the positions of the bottles are reversed. Accordingly the bottles which have been washed are now rinsed while the other pairs of bottles are being washed. The arrange ment is such that the machine can be run continuously and a muchgreaier number of bottles both washed and rinsed than is possible in any of the present types of washing machines now in use.
